Abstract: 1, 080, 534. Automatic temperature control systems. SIEMENS-ELECTROGER€TE G.m.b.H. Sept. 11, 1964 [Sept. 17, 1963], No. 37368/64. Heading G3R. A temperature sensor in an automatic heating system comprises at least two temperature dependent resistors each of which is arranged to predominate over a different part of the temperature range. A negative characteristic resistor 1 controls a regulator R in the lower part of the range another negative characteristic resistor 2 being short circuited by a positive characteristic resistor 6. In the upper part of the range the resistor 6 has a high resistance hence the resistor 2 predominates in controlling the regulator R. Other arrangements are described in the Specification. The resistor 6 preferably has a "knee" in its temperature characteristic.

Abstract: 1,028,749. Coaster cycle hubs. FICHTEL & SACHS A.G. Sept. 25, 1963 [Sept. 26, 1962; Nov. 8, 1962], No. 37720/63. Heading B7E. A free wheel back pedalling cycle hub, Fig. 1, comprises bearing ring bodies 12, 14 mounted on the spindle 10, a drive wheel 20 and member 18 supported on the body 12 and a bearing 16 on the spindle, a screw body 30 screw-threaded on the member 18, a hub sleeve 26 which may in a right-hand position of the body 30 be driven thereby, and a brake casing, Fig. 3, having bevelled resilient tongues 32 integral with the ring body 14 and formed by cold pressing and punching. When forward pedalling, the body 30 is screwed to the right on the member 18 by the thread 28, since it is hindered from rotating by the grip-spring 33, and the surfaces 38, 40 engage to drive the hub sleeve. When the drive member 18 is stationary as in free-wheeling, the body 30 is entrained by the hub sleeve and moved to the left until the drive is disengaged. When back pedalling, the body 30 is hindered from rotating by the grip spring 33 and is shifted to the left to spread out the tongues 32 against the hub sleeve. In Fig. 2 the screw body 58 is for drive only and is controlled by a grip-spring free wheel 62, braking being obtained on back pedalling by the spreading of rollers 68 against the tongues 32. In Fig. 7 the screw body is integral with the tongues and forms the brake casing, a gripspring free wheel 78 being provided between the tongues and a surface 70 of the ring 14. The surfaces 70 and 76 may be provided with teeth.

Abstract: An isoolefin-diene copolymer having an average molecular weight of at least 200,000 and a mole per cent unsaturation of less than 5% is modified by forming an intimate mixture of 100 parts by weight of the copolymer with from 0,5-100 parts by weight of one or more conjugated diene, vinyl, vinylidene or allyl monomers and effecting polymerization of the monomeric material with the aid of a free-radical-generating catalyst.  Copolymers specified are isobutylene-isoprene rubbers.  Monomers specified are vinyl and vinylidene halides, acrylic and methacrylic acids and their nitriles, amides, C1C18 alkyl, including cycloalkyl, esters and esters with unsaturated and polyhydric alcohols, vinyl acetate, vinyl allyl and methallyl esters of saturated and unsaturated mono- and poly-carboxylic acids, divinyl benzene, styrene and alkyl derivatives thereof, vinyl pyridines, vinyl carbazole, mono- and poly-unsaturated ketones and ethers, acrolein, methacrolein, crotonaldehyde, butadiene, isoprene, dimethyl butadiene, cyclohexadiene and diallyl aryl phosphonates. Polymerization may be carried out in solution, aqueous emulsion or in bulk.  Catalysts specified are organic and inorganic peroxides which may be used in conjunction with a reducing agent to form a redox system.  The properties of the resulting products are determined by the nature of the modifying monomer. Products containing reactive hydrogen atoms may be reacted with diisocyanates or epoxy resins, e.g. those formed from epichlorohydrin and polyphenols or polyamines.  The products find particular application as adhesives, for which purpose they are used in solution or latex form in admixture with substances such as phenoplasts, e.g. a resorcinolformaldehyde resin, aminoplasts, condensation products of amines with aldehydes and ketones, natural rubber, polybutadiene, butadiene copolymers, polystyrene, polyvinyl chloride and polymethacrylates.  After application, e.g. to fibres, the adhesives are cured by heating.ALSO:Fibres and cords, e.g. those of rayon, cotton, nylon, polyacrylonitrile or polyethylene terephthalate, are coated with an adhesive comprising (1) an iso-olefin-diene copolymer having an average molecular weight of at least 200,000 and a mole per cent unsaturation of less than 5%, e.g. butyl rubber, which has been modified by polymerizing therewith an unsaturated monomeric material, e.g. unsaturated acids, amides, nitriles, esters, hydrocarbons (including unsaturated aromatic and dienic hydrocarbons), halogenated hydrocarbons, aldehydes, ethers, ketones and heterocyclic compounds (see Group IV(a)), in admixture with (2) a coating adhesive component such as a phenoplast, e.g. a resorcinol-formaldehyde resin, an aminoplast or the reaction product of an amine with an aldehyde or ketone, and optionally (3) other polymers such as natural and synthetic rubbers, polystyrene, polyvinyl chloride or polymethacrylates.  The adhesive is applied to the fibres either in the form of a solution in an organic solvent or as an aqueous latex and then cured by heating.

Abstract: 905,168. Transferring block-like articles from a rotary conveyer to a linearly moving conveyer. DORSTENER EISENGIESSEREI UND MASCHINENFABRIK A.G. Nov. 4, 1960 [Nov. 6, 1959], No. 37924/60. Class 78 (1). In apparatus comprising one or more grippers 32/33 rotatably mounted on axes 31 in a carrier arranged to be swung in a vertical arc from the full-line position over a rotary table 2 to the chain-line position over a belt conveyer 7, the grippers are alternately rotated to opposite sides of a pick-up position I in which they are radially arranged with respect to the table, during successive swinging movements of the carrier, to positions II, III corresponding to final positions of the blocks side-by-side on the conveyer 7, by mechanism adapted to locate the grippers positively in each of the said positions I, II, III. This mechanism consists of a onearmed lever 3 secured to the axis 31 of each gripper for rotation therewith, adjustable stops 9, 9a for locating the lever in positions corresponding to the positions II, III, respectively, and a rotatable cam assembly 8 co-operating with each lever 3, and operating cylinders 6, 11, the former having their piston-rods 5 connected to toothed rotatable segments 4a engaging toothed segments 3a on the respective levers 3 for rotating the grippers, and the latter being coupled by its piston-rod 12 and a connecting- rod 10 of adjustable length to the cam assemblies 8. Each cam assembly comprises a pair of cams 8c, 8d adjustably secured together to provide a desired spacing between their abutment faces 8a, 8b. In operation the cylinders are actuated such that as the grippers are returned from position II or III to the position I the cam assembly is rotated to present the appropriate abutment face 8a or 8b to stop the lever 3 in the position corresponding to the position I, the fluid-pressure being maintained in the cylinders 6 at each working position of the grippers. Each of the adjustable stops 9, 9a consists of an eccentric which is rotatable by a pivoted sector-plate 16 having a slot for locking it in position by means of a bolt 17. Specification 905,167 is referred to.

[Also in Division H4] A frequency-modulated light receiver for an optical doppler radar comprises means responsive to an input light beam to produce a further light beam of the same wavelength as the input beam and of constant intensity and means responsive to the further beam for decoding information encoded as variations of frequency of the input beam. The frequency modulated input beam 9 is divided by beam splitter 22 to fall on photomultipliers 28, 42. Photo-multiplier 28 has an S1 photo-cathode giving it a response substantially independent of wavelength around 700 nm, and its output which is simply intensity dependent is compared with a reference signal 38 and any difference is used to energize a motor 16 to adjust an aperture or Kerr cell attenuator 18 to keep the intensity falling on the photo-multipliers constant. Photo-multiplier 42 has an S20 photocathode which has a marked variation is sensitivity with wavelength and produces an amplitude modulated signal corresponding to the frequency modulated input light beam. This signal is applied to an indicator 48 calibrated in target speed. A filter 20 is provided to limit bandwidth and so reduce noise.
